4. AND2 is the third FB because it has a predecessor (see 3.)

5. Accordingly, the entries under C0465 are as follows:

– Position 10: AND1 10500

– Position 11: OR1 10550

– Position 12: AND2 10505

The example starts with position 10 because these positions have not been assigned with the default
setting.

The FBs need not be entered directly one after the other in the processing table. Empty positions are
permitted.
